    [SINGAPORE] Data centre provider ST Telemedia Global Data Centres (STT GDC) opened its first facility in South Korea on Tuesday (Jun 16), launching a 30-megawatt site in Seoul to capture surging demand for artificial intelligence and cloud infrastructure.

    The new facility, STT Seoul 1, begins full commercial operations this month. It is operated through a joint venture between the Singtel and KKR-backed STT GDC, which holds a 60 per cent stake.

    South Korea’s Hyosung Heavy Industries holds the remaining 40 per cent. Hyosung specialises in power transmission, distribution solutions and renewable energy.

    The launch marks a strategic push into North-east Asia for STT GDC, expanding a global footprint that includes operations in Singapore, Malaysia, Indonesia, Japan, India and the UK.

    The Seoul opening comes less than a week after the company announced plans to expand its Jakarta operations to meet rising regional digital and cloud demand.

    Spanning about 40,000 square metres of gross floor area in Seoul’s Geumcheon district, the facility targets hyperscale and enterprise clients scaling high-density AI workloads.

    Appealing to corporate clients with strict efficiency and reliability mandates, STT Seoul 1 has a design power usage effectiveness of below 1.3 and is equipped with dual 22.9 kilovolt power feeds, alongside backup generators capable of operating for up to 24 hours without refuelling.

    “AI infrastructure demand is increasingly concentrating in markets where digital capability, power availability and customer requirements come together,” said Charles Chulhoy Huh, STT GDC’s country head for South Korea.

    “STT Seoul 1 establishes an important foundation for STT GDC’s presence in (South) Korea, extending a globally consistent platform into a key North-east Asian market.”

    Wong Kai Jiun, Singapore’s ambassador to South Korea, noted at the event that trusted digital infrastructure will play a crucial role in enabling deeper cross-border connectivity and collaboration as both nations advance their digital economies and AI capabilities.
